This work characterises the high-quality white marble used in the bust of Emperor Hadrian found in the Roman villa of Los Torrejones (Yecla, Murcia). The analytical results, compared with the databases pertaining to Hispanic and Mediterranean quarry marbles, reveal its source in the quarries of Göktepe, in Muğla province, Western Turkey. The historical implications of the presence in the villa of an imperial portrait of such quality are discussed. The results also emphasise the importance of undertaking future complete archaeometric analysis of marble materials used in the sculptures of Hispania, only way to certify the provenance of the stone and, in this case, to better understand the distribution reached by the varieties of Göktepe marble in the Iberian Peninsula.
